Minor Use Label Expansion Granted For Assail 70 WP Insecticide for Control of Aphids on Succulent Peas and Beans

J. Chaput, OMAFRA, Minor Use Coordinator, Guelph

The Pest Management Regulatory Agency (PMRA) recently announced the approval of a minor use label expansion for ASSAIL 70 WP insecticide (acetamiprid) for control of aphids on succulent shelled peas and beans, crop subgroup 6B in Canada. ASSAIL 70 WP (acetamiprid) was already labeled for management of a variety of insect pests on a range of crops in Canada.

The minor use submission for succulent peas was sponsored in 2007 by the Agriculture & Agri-Food Canada, Pest Management Centre (AAFC-PMC) and the minor use submission for succulent beans was sponsored in 2011 by the Quebec Horticultural Council (CQH) in response to minor use priorities identified by pea and bean producers and extension personnel in Canada.

Aphids have been a troublesome pest of succulent pea and bean crops in Canada in recent years. Management of this insect pest has been a high priority for succulent pea and bean producers and the registration of Assail insecticide will provide producers with an effective and useful insect management and resistance management tool.

The following is provided as a general outline only. Users should consult the complete label before using Assail 70 WP insecticide.

For control of aphids on succulent peas and beans, apply 56 – 86 g per hectare of Assail in a minimum finished spray volume of 200 L water per ha. Begin applications when insect populations reach economic threshold levels and apply at 7 day intervals. Do not use more than 3 applications per season and do not apply less than 7 days before harvest of succulent peas and beans.

Assail insecticide should be used in an integrated pest management program and in rotation with other management strategies. Follow all other precautions and directions for use on the Assail insecticide label.

We wish to acknowledge the personnel of Nippon Soda Co. Ltd. and DuPont Canada Inc. for their support of this registration and the personnel of the Pest Management Regulatory Agency for evaluating and approving this important pest management tool.
